TRUSS.

Application filed DecemberSO, 1926. Serial No. 157,957.

This invention relates to new and useful improvements in a truss.

One object of the invention is to provide a truss of the character described including an adjustable pad so mounted that it may be readily adjusted to any position, relative to the abdominal wall and there secured in a fixed position.

Another object of the inevntion is to provide atruss of the character described having a novel type of hernial pad, of novel construction which may be cheaply and easily produced and readily adjusted, and which may be worn with comfort. 7

With the above and other objects in View this invention has particular relation to certain novel features of construction, arrangement of parts and use, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a front elevation of a complete truss, as applied to the body of a wearer.

Figure 2 shows an enlarged transverse sectional view of the hernial pad.

Figure 3 shows an enlarged fragmentary side elevation of the body clamp, and

Figure 4 shows a sectional view thereof taken on the line ee of Figure 3.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures the numeral 1 designates a body clamp, preferably formed of a flexible steel rod, or other suitable flexible material and U-shaped in general contour so as to clamp around one side of the body. Attached to the rear end of this body clamp is a. back pad 2 designed to rest against the back of the wearer and the free end of the front arm of the body clamp carries the hernial pad designated generally by the numeral 3. This lOOdy clamp is formed of two sections whose adjacent ends overlap and are fitted through a clamp collar 4 and are retained therein by means of a suitable clamp screw 5 in an obvious manner. This screw may be loosened and the body clamp adjusted as desired.

The numeral 6 designates the hernial pad which is preferably disc-like in form and is composed of soft rubber or other suitable soft material. This pad is enclosed in a fabric sack or cover 7. The outer side of the pad 6 has a concaved seat in which rests the convex face of the concavo-convex nut 8 and there is a disc-like clamp plate 9 backing the disc 6 whose margin 10 is overturned toward said disc and whose central portion is of concave-convex formation to conform to the contour of and to seat within the concave surface of the nut 8, and said disc has a relatively large central opening 11. There is a hemispherical clamp block 12 having its convex face fitted withinthe concaved portion of the clamp plate 9 and a clamp bolt is fitted through a central bearing in the block 12 and threaded through the nut-8, said bolt having an enlarged head 14L and this belt clamps the adjacent parts in assembled relation and its outer end is formed with-a socket 15 to receive a suitable socket wrench for manipulating thesame.

There is an annular clamp Washer 16 whose inner margin 17 1S outwardly turned and rests against the margin of the nut 8 and whose outer margin clamps the adjacent.

clamped between said head'and the clamp block 12 and this supports the hernial pad in position.

It is obvious that a ball joint is formed between the clamp block 12 and'the disc 9'to the end that-when the clampbolt 13 is'loosened said pad may be adjusted in any desired position, one ad usted pos1tion being indicated by dotted lines in Figure 2, and

when said clamp bolt is tightened the hernial pad will be held securely in said adjusted position. In making these adjustments the nut 8 maintains itself in fixed relation with the clamp block 12, the clamp washer 16 being forced by said nut into eccentric position relative to the clamp plate 9 but maintaining itself in clamping relation with the margin of the fabric covering 7 and all parts are securely held in the selected position when said clamp bolt 13 is tightened. The body clamp 1 is retained in position by means of the strap .19 fastened to the rear side of said clamp above the body pad 2 and attached to the front side of the clamp 1 adjacent the hernial pad and this strap may be adjusted to the body by means of the usual buckle 20.

betweenwhich-the margin of said coveris clamped, a clamp block and a clamp nut be tween which said plate is clamped, the outer margin of said nut resting against the inner margin of the washer, a-clamp bolt passing through theblock and onto which said nut is threaded. I v

2. In atruss a hernial pad having a sack-, like cover, a concave-convex clamp nut with itsconrex side adjacent said pad, a clamp plate having a concave-convex central portion which fits within the concave side of said nut, a clamp block fitted into the concaved portion oiisaid plate, a clamp washer whose inner margin rests against the margin 01 said nut, said plate and washer clamping the margin of the pad cover between them, a clamp boltflpassing through said block and plate and having a threaded con nection with said nut.

Sfln a truss a hernial pad havingasacklike cover, a concavo-convex clamp nut abutting said pad and having its convex side adjacentsaid'pad, a clamp plate having a concavo-conven portion which. fits within the concave side of said nut, a clamp block fitted into the concaved portion of said plate, a clamp washer whoseinner margin rests againstthe margin of-said nut, said plate and washer clampingthe margin of the pad cover between them, a clamp bolt passing through said block and plate and having a threaded connection with said nut-,the outer end of saidbolt'having an enlarged head and a, body clamp, one end of which is formed with aneye which surrounds said bolt and isclamped between said liead and block.

' at. In a truss a 'hernial pad, a clamp nut adjacent the pad,a clamp plate adjacent the outer side of said nut, a clamp .washeraround plate and with which the nut has a threaded -connect1on.

5. In atr'uss a hernial pad, a clamp nut adjacent the pad, a clamp plate adjacent the outer side oi? said nut, a clamp washer around an in contact with thenut, said nut 'forming the only means for holding the washer in clamping relation with said plate,

a pad co -y ering having its 'nrginclampect bctw en the plate and washer, a clamp block resting against the outer side or" said plate, a

clamp bolt passing through said'blocl: and

plate and with which the nut has a threaded connection and a flexible body clamp toone end of which the outer end of the bolt is connected. I r

(3. ln a'truss a padhaving an annular'free margin, a clamp plate forming a'rigid back for the pan, the central portionof the clamp plate having an opening with the margin of the olate aroundsaid opening being curved inwardly toward the pad and the outer margin of said clamp plate overlying said annular tree portion of the pad, a

clamp block having a convex face which works against theinwardly turned margin of said. clamp plate, an annular clamp washer whose outer maiifgin fits against the inner side of the annular free margin 01 said pad, i

said washer having a central opening with the margin around said central opening turned outwardly toward said olampplate, a nut having a, bearing against the inner side of said outwardly turned margin of said washer and aclamp bolt fitted through said 7 clamp block and having a threaded connection with said nut.

In testimony whereof I have signed my name to this spec1ficat1on.
